My XAH "quit" for 4 months. I think the first month was white knuckling it. The next three months were lying and telling his friends "my wife thinks I'm an alcoholic".
Bottom line is: if he doesn't WANT to quit, he won't. Ever. No threats, no tears, no begging, no pleading and no baby will change that. And two weeks of not drinking isn't going to make him surrender to alcoholism. He isn't going to forget about drinking that beer on day 15 - he's only going to very eagerly await it (IF he actually waits that long). I remember SOOOO well thinking that OUR situation was different. It wasn't. It only really became different when I accepted it and started focusing on ME rather than "him" or even "us".
